I'm new to linux and I installed ubuntu 11.10 x64. I got a HP Envy 14 laptop (i7 second gen) and my batterytime is half the uptime I get in windows 7. Now I got 2hours and it discharges in 30w. In windows I get about 4-5 hours uptime.

I have done some guides so I only use the integrated graphicscard. I ran powertop and pasted it here below, if someone can get something out of it.. seems strange with a lot of posts on 100%. I dont know what to look for :/

In powertop, go to the last tab and try enabling some tweaks to lower power consumtion, also, installing Jupiter might help, (I reccomend searching it at webupd.org since they have a PPA with newer versions that in the Ubuntu Repos), also, search for propietary drivers, as they may lower heat and power consumption on your laptop. Go to System Settings and try to set it up to a more power-saving setting.
